Writing and music are creative endeavors. If you try to make them your livelihood then they become jobs. And you better be very good at what you do and spend plenty of time on promotion and business. But these take time away from your art/creativity. It is a difficult balancing act.
When Pink Floyd was coming up the music business was vastly different than it is now. Record labels were the gatekeepers. They did the bulk of album promotion. Pink Floyd also had a business manager who took care of all the business aspects like booking tours and promoting them. And a lawyer to handle finances. The band wrote songs, recorded, and toured. Performing live is a form of promotion, but it is also what musicians live for so it doesn’t feel like promotion. Pink Floyd as a band focused on the creative side of the process and this allowed them to create a masterpiece of an album. Dark Side Of The Moon.
Now, most musicians and writers are expected to do everything themselves and still be creative. It is overwhelming. And very difficulty to master it all. Which is why many have other jobs. It frees them to be creative without the pressure of income.
I think Medium is a great method of promotion. It is like gigging for musicians. You keep at it and you slowly build a following. Everyone wants an audience. An audience let’s us know what is working or not. And gives us satisfaction when something is popular.
Some writers write as a job, writing things they may not care about for pay. There is absolutely nothing wrong with that. We all need to eat. Some writers write to express their creativity. Money is secondary. Some rare, fortunate ones make a living expressing their creativity. I hope you become one of the rare ones, Vico.
